Why this critique is called simply Critique of Practical Reason and not Critique of Pure Practical Reason, though the parallelism between it and the critique of speculative reason seems to demand the latter title, will be sufficiently shown in the treatise itself. Its task is merely to show that there is a pure practical reason, and, in order to do this, it critically examines reason's entire practical faculty. If it succeeds in this task, there is no need to examine the pure faculty itself to see whether it, like speculative reason, presumptuously overreaches itself. For if pure reason is actually practical, it will show its reality and that of its concepts in actions, and all disputations which aim to prove its impossibility will be in vain.Leer más

Resumen:

Why this critique is called simply Critique of Practical Reason and not Critique of Pure Practical Reason, though the parallelism between it and the critique of speculative reason seems to demand the latter title, will be sufficiently shown in the treatise itself. Its task is merely to show that there is a pure practical reason, and, in order to do this, it critically examines reason's entire practical faculty. If it succeeds in this task, there is no need to examine the pure faculty itself to see whether it, like speculative reason, presumptuously overreaches itself. For if pure reason is actually practical, it will show its reality and that of its concepts in actions, and all disputations which aim to prove its impossibility will be in vain.
